When the display unit 151 is implemented as a touch screen, the display unit 151 may function as the user input unit 123, so that the main unit 110 may not have a separate key.

The strap 120 is worn on the wrist so as to enclose the wrist and may be formed of a flexible material for easy wearing. As an example, the strap 120 may be formed of leather, rubber, silicone, synthetic resin, or the like. On the other hand, the strap 120 can be used to expand the performance of the antenna. For example, the strap 120 may include a ground extension (not shown) that is electrically connected to the antenna and extends the ground region.

The strap 120 may be provided with a fastener 102a. The fastener 102a may be embodied by a buckle, a snap-fit hook structure, or a velcro (trademark), and may include a stretchable section or material . In this drawing, an example in which the fastener 102a is embodied as a buckle is shown.

The strap 120 may be detachably attached to the main body 110 so that the strap 120 can be replaced with various straps 120 according to the user's preference.

FIG. 2 shows an embodiment of a conventional spring type strap interchangeable smart watch 100, and FIG. 3 shows an embodiment of a conventional screw type strap interchangeable smart watch 100. As shown in FIG.

The smart watch 100 may include a main body 110 on which electronic components are mounted and a strap 120 connected to both sides of the main body 110 and wound around a user's wrist.

In the case of a general strap interchangeable smart watch 100, it is generally composed of a watch pin 310 detachable from the main body and a strap 120 fitted to the watch pin 310. The strap 120 can be pulled out only by inserting the watch pin 310 into the hole provided at one end of the strap 120 and separating the watch pin 310 from the body.

Referring to FIG. 2, in the case of the spring-type watch pin 310, the protrusion 311 protruding inward in the longitudinal direction of the watch pin 310 is pulled and separated from the main body 110.

3, in the case of the screw type watch pin 320, one of the screws 321 of the watch pin 320 may be separated to separate the watch pin 320 from the main body 110 have.

Both the spring-watch pinning method and the screw-watch pin method must be separated by a separate auxiliary tool.

4 is a perspective view of the smart watch 100 related to the present invention.

The main body 110 may include a front portion or a display portion of the smart watch 100. However, since the strap 120 to be described later can be used not only for the smart watch 100 but also for a general purpose analog watch or a digital watch, the main body 110 does not necessarily have a display unit.

The pair of fixing holes 112 may be provided so as to face one end of the main body 110. The pair of fixing holes 112 may be formed inside a pair of extension portions 111 formed at one end of the main body 110.

One end of the main body 110 may refer to at least one of an upper end and a lower end of the main body 110 of the smart watch 100. The fixing holes 112 are provided on both sides of the upper and lower ends of the main body 110 so that the straps 120 can be attached to and detached from both sides of the main body 110. For convenience of explanation, only one side of the main body 110 is described, It is a principle that one end of the main body 110 is provided symmetrically with both the upper end and the lower end of the smart watch 100.

One end of the strap 120 may be provided with a pair of fixing pins 220 protruding on both sides. The pair of fixing pins 220 are inserted into the pair of fixing holes 112 of the main body 110 so that the straps 120 can be fixed.

When the pair of fixing pins 220 are engaged or disengaged from the main body 110, the pair of fixing pins 220 can be compressed. When the compressed fixing pin 220 is engaged with the fixing hole 112, it can be pulled by the restoring force and fit into the fixing hole 112.

The fixing pin 220 may be attached to and detached from the main body 110 by engaging with the strap 120 through the fastening module 200. The fastening module 200 may be a component of the strap 120 as needed.

5 is an exploded rear perspective view of the smart watch 100 related to the present invention.

The fastening module 200 may be provided in the strap 120 to allow the main body 110 and the strap 120 of the smart watch 100 to be attached and detached. However, the fastening module 200 may not be provided independently of the strap 120, but may be integrally formed with the strap 120 within the scope of the present invention.

The fixing pin 220 is tensioned or compressible so that it protrudes to both the left and right sides of the fastening module 200 or the strap 120 in tension so that the fastening module 220 or the strap 120 does not protrude from both sides of the fastening module 200 or the strap 120, can do.

The elastic member 230 may be coupled to the fixing pin 220 and may be deformed by a force acting in one direction of the elastic member 230 to compress the fixing pin 220.

The one direction may be a direction perpendicular to one surface of the strap 120 of the smart watch 100.

The user may apply a force to the slider 260 in a direction perpendicular to one surface of the strap 120 to compress the fixing pin 220 to separate the fixing pin 220 from the fixing hole 112. [

Alternatively, the fixing pin 220 separated from the fixing hole 112 may be compressed to be coupled to the fixing hole 112.

However, one direction may be a different direction if necessary within the scope of the concept of the present invention. That is, the strap 120 may be provided in a direction in which the user can easily press, such as being inclined at a predetermined angle in a direction perpendicular to one surface of the strap 120.

The user can merge or separate the main body 110 and the strap 120 with a simple operation of pressing one area of the one side of the strap 120.

This pressing operation can be implemented through the button surface 261 provided on the slider 260. [ The button surface 261 may be provided on the slider 260 so as to be perpendicular to a direction in which the slider 260 is urged.

The button surface 261 may be exposed to the one-side opening 121 of the strap 120. One side of the strap 120 from which the button surface 261 is exposed may be the inner side of the strap 120, i.e., the back side 1202 of the strap 120. If the button surface 261 is exposed on the rear surface 1202 of the strap 120, the smart watch 100 can be prevented from being exposed to the outside when the user wears it.

The button surface 261 may form the same surface as one surface of the strap 120 without the slider 260 being in an unpressed state.

The button surface 261 may include a sufficiently wide surface so that the user's fingertip can be pressed without inconvenience.

The elastic member 230 may be provided in the form of a wire. In particular, the elastic member 230 may include a metal wire.

The elastic member 230 may have a left-right symmetrical shape with respect to the direction in which the fixing pin 220 is compressed, that is, the width direction. When the slider 260 is pushed, the elastic member 230 can increase in length in the longitudinal direction and decrease in width in the width direction. The fixing pin 220 coupled to the elastic member 230 having a reduced width can be compressed to the same displacement.

In particular, the elastic member 230 may have a "V" shape or a "U" shape. Or may be in the form of a combination of complex shapes including a plurality of regions of bends 232 as in the embodiment of FIG.

The inclined portion 231 may mean an inclined region in which the width becomes narrower toward one end in each of both ends of the elastic member 230. The inclined portion 231 may play a role of keeping the overall shape so that the distance between the compression portions 234 is not long and the bent portion 232 at one end of the elastic member 230 is formed.

At least one region of the bending portion 232 may be a region where the shape of the elastic member 230 is directly deformed. The bent portion 232 may be a vertex at which the linear region of the elastic member 230 meets, or may be an entirely curved region.

The elastic member 230 may have a restoring force to return to the original shape after the shape of the elastic member 230 is deformed or deformed due to at least one bent region of the elastic member 230. [

The restoring force may vary depending on the thickness and the size of the elastic member 230. However, the thickness and the size of the elastic member 230 may be limited to minimize the increase in the thickness of the strap 120 due to the elastic member 230.

6 is a cross-sectional view taken along the line A-A 'in FIG.

The compression portion 234 can be in contact with the pressing portion 262 of the slider 260. The compression unit 234 may receive a force in one direction acting on the slider 260 to compress the elastic member 230.

The compression portion 234 is symmetrically formed as described above and can behave in the same direction as the compression or tension direction of the fixing pin 220. [

That is, when the compression unit 234 is compressed on the basis of the left-right direction of the smart watch 110, the fixing pin 220 is compressed. On the other hand, when the compression unit 234 is tensioned, .

The symmetrical compression portions 234 may be provided parallel to each other. That is, the compression section 234 may include a linear region perpendicular to the compression direction.

The linear region perpendicular to the compression direction of the compression portion 234 can increase the efficiency so that the force of the pressing portion 262 of the slider 260 can be used for the force to be fully compressed.

The pressing portion 262 of the slider 260 may have a shape corresponding to the pressing portion 234 of the elastic member 230. That is, the pressing portion 262 and the pressing portion 234 are in contact with a line or a surface other than a point, so that the pressing force is dispersed and transmitted to stably compress the elastic member 230.

The pressing portion 262 of the slider 260 may contact the two outer points of the elastic member 230 and form an inclined surface along one direction. The degree of inclination of the inclined surface can be determined by factors such as the stroke distance of the slider 260 and the distance between the compression portions 234 of the elastic member 230 and the like.

In order to minimize the loss of force in converting the pressing force acting on the slider 260 into the pressing force of the elastic member 230, a slope of about 45 degrees with respect to one surface of the strap 120 may be appropriate .

The fixing pin 220 may be provided with two separate left and right pin members. The support hole 212 may be formed in each of the pair of fixing pins 220 so that both ends of the elastic member 230 pass through.

The restoring force of the elastic member 230 may play a role not only to tension the fixing pin 220 but also to restore the button surface 261 of the slider 260 to the original state.

 7 is a rear perspective view of another embodiment of a portion of a smart watch 100 fastening module 200 in accordance with the present invention.

As shown in FIG. 5, the elastic member 230 may be a separate member from the fixing pin 220, but may be integrally formed. In particular, the fixing pin 220 and the elastic member 230 may be formed of an integral wire. When the elastic member 230 and the fixing pin 220 are integrally formed, material cost and production cost can be reduced.

The remaining features of FIG. 5 may be similarly applied, other than the feature that the elastic member 230 is integrally formed and performs the role of the fixing pin 220 at the same time.

8 is a rear exploded perspective view of the smart watch 100 fastening module 200 according to the present invention.

The base frame 210 can mount at least a part of the configuration of the elastic member 230, the slider 260, and the pair of fixing pins 220. When the elastic member 230 and the slider 260 are directly mounted on the strap 120, the strap 120 may receive an unintended force due to the ductility of the strap 120, so that the base frame 210 can be stably positioned can do.

The bushing hole 211 is provided in the base frame 210 and is inserted into the fixing pin 220 to guide the displacement for compressing or tensioning the fixing pin 220. The stepped portion 220 may be formed so that the inner diameter of the fixing pin 220 is larger than the outer diameter of the fixing pin 220, thereby preventing the fixing pin 220 from falling out of the bushing hole 211. The fixing pin 220 is inserted into the elastic member 230 to primarily restrict the displacement and prevent the displacement of the fixing pin 220 from being deviated from the outside due to the secondary limitation by the step portion 221 of the fixing pin 220 can do.

The seating part 215 may be formed with a step on the base frame 210 to prevent the slider 260 from being coupled to the base frame 210 to flow. The step boundary of the seating part 215 may be provided in the same manner as the outer boundary of the slider 260. [

The base frame 210 may form the first hook portion 271. The first hook portion 217 can form a boundary of an opening through which the button surface 261 of the slider 260 is exposed.

The slider 260 may include a second hook portion 263 engaged with the first hook portion 271. The second hook portion 263 may be hooked on the first hook portion 271 to prevent the slider 260 from falling outward and to be engaged with the base frame 210.

The slider 260 may have rigidity such as polycarbonate or polyamide and may have a certain degree of ductility to be coupled to the base frame 210 in the vertical direction.

Alternatively, the insertion hole 272 of the slider 260 and the second hook portion 263 may be inserted in a slidable manner and then slid by a predetermined distance in the lateral direction perpendicular to the pressing direction.

9 is a front perspective view of yet another smart watch 100 fastening module 200 in accordance with the present invention.

The fastening module 200 may be coupled to the strap 120. The strap 120 and the fastening module 200 may be bonded by applying an adhesive tape or an adhesive material. When the strap 120 is coupled to the fastening module 200 by applying an adhesive tape or an adhesive material so that the slider 260 is exposed to one side of the base frame 210, There is a risk of being fixed so that it can not be displaced.

In order to solve the above-described problems, the cover frame 250 may be provided to cover one area of the front surface of the fastening module 200. In particular, the cover frame 250 covers at least one region of the boundary between the slider 260 and the base frame 210 and the entire front surface of the slider 260 to prevent the slider 260 from being fixed by the adhesive material .

A coupling protrusion 216 is formed on the front surface of the base frame 210 and a coupling hole 251 corresponding to the coupling protrusion 216 is formed on the cover frame 250, 250 can be stably coupled.

It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

It goes without saying that the present invention can be applied not only to the smart watch 100 but also to a wearable device including all general-purpose watches having the same type of strap combination as described above.

The foregoing detailed description should not be construed in all aspects as limiting and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
